What is HD Ready and Full HD
If you connect to the TV using HDMI from the PC as long as the audio is set to output to HDMI you should get sound. If your graphics card does not support sound over HDMI then you will have to connect up using the analogue out from your PC sound card to the TV. The same applies whether it is the iplayer or any other video player you are getting to play from the PC to TV.
